Once the underside of the platter begins to take shape, you can turn your attention to the rim (figure A).It's at this stage that you'll decide how wide the rim needs to be and where the base of the curve begins.
Steps1. As the curve of the bottom begins to take shape, the focus changes to thinning the rim and deciding how wide it needs to be at the front, where the base of the curve begins (figure B). The rim must maintain a solid thickness or it will affect final design choices: if it is turned too thin at this stage, the design can never be modified or have a finger rim or handle formed. 2. Clean the surface with the tool on its side; it doesn't have bevel contact, but it does have the long cutting edge sliding along the tool rest, smoothing any waves or uneven surfaces on the blank (figure C).
3. Shear torn fibers by holding the tool up, using the same cutting edge as in step 2; held at a steeper angle, the tool will cleanly shear off any remaining fibers (figure D).4. With the surface clean, turn the curve, creating a sharp bead that moves into a cove shape, leaving approximately 1/4" thickness at the rim (figure E).
